摘要： A thermal trip assembly is for an electrical switching apparatus. The electrical switching apparatus includes a housing, separable contacts enclosed by the housing, an operating mechanism for opening and closing the separable contacts, and a number of shunts. The thermal trip assembly includes a load conductor, a bimetal adapted to cooperate with the operating mechanism to open the separable contacts in response to a trip condition, and a bypass heater element structured to be electrically connected to the shunts. The bypass heater element directs the flow of electric current to at least partially bypass the bimetal.

摘要： An electrical protection switch, or circuit breaker, includes a movable contact part rotatably seated on a bolt which is secured to a leg of a mount. The other leg of the mount lies against a flange of a coil member which forms a portion of a magnetic release means. Two retaining elements extending parallel to one another and mutually spaced apart project from this flange. The retaining elements accept one leg of the mount therebetween and are provided with resilient tongues which press against the leg of the mount lying against the flange and, thus, press the leg against the flange. Fastening of the mount having the movable contact part to the magnetic release means, or coil member, is performed simply by slipping the mount onto the coil member by a snap-in connection.

摘要： A circuit interrupter responsive to abnormal currents in conductors of an electrical distribution system characterized by a circuit breaker mechanism for opening and closing separable contacts and which mechanism comprises a releasable member operable between latched and unlatched positions, trip means comprising a bimetal element and a trip bar movable to unlatch the circuit breaker mechanism and biased in the latched position, the trip bar having a surface facing and spaced from the bimetal element which surface is slanted at an oblique angle to the longitudinal axis of the trip bar, and manually adjustable knob connected to the trip bar for sliding the trip bar longitudinally to vary the space between the bimetal element and the trip bar surface in accordance with a desired thermal rating.

摘要： A low voltage circuit breaker in a moulded case comprises a breaker unit (10) and a remote control unit coupled to it that controls the swing of a bistable movable contact (22) housed in the breaker unit. A trip mechanism (50) cooperates with movable contact (22) in the case of a fault to swing movable contact (22) into open circuit position independently of the remote control mechanism (48). A resetting handle (88) must be actuated in order to render the circuit breaker reoperative.
